Subject: [PATCH] gnu: python-axolotl: Update to 0.1.39 and fix build.
Date: Thu, 23 Nov 2017 15:04:46 -0500

Patch taken from the debian package for python-axolotl-0.1.39.

python-axolotl has been failing since March,
https://hydra.gnu.org/job/gnu/master/python-axolotl-0.1.35.x86_64-linux

This also fixes the OMEMO and OTR plugins for Gajim work.
